Visual field defects
Visual field defects refer to partial or complete loss of vision in specific areas of a person’s visual field. This can occur for various reasons, such as damage to the eye, optic nerve, or parts of the brain responsible for processing visual information. Common types include tunnel vision, where side vision is restricted, or blind spots where vision is absent. These defects can greatly affect daily activities like reading or driving and may result from conditions like glaucoma, strokes, or brain tumors. Diagnosis typically involves specialized eye exams to determine the extent and cause of the defect.
